Solution
The correct answer is C. A lichen is composed of a fungus and a protobiont. The protobiont is most likely to be a green alga or a cyanobacterium. This is because lichens are symbiotic associations between a fungus and a photosynthetic partner, which is usually either a green alga or a cyanobacterium. The photosynthetic partner provides the fungus with nutrients, while the fungus provides a protective environment for the photosynthetic organism.
